mrtg bug was fixed upstream but is not available in stable or unstable ubuntu or debian packages

[schoutetens]

mrtg sends an email to root every time it's called because of an error. As far as I understand, this error has been fixed by mrtg months ago but is still not included in the packages system:
v2.17.3 (2011-12-01): latest stable release
v2.17.1 (2011-02-18): bugfix for the problem related to this bugreport
v2.16.3 (2010-01-20): version included in the packages

due to the nature of mrtg (collecting data) it's called every 5 minutes, resulting in 288 mails/day.
I believe this bug showed up on my system after an APT-triggered perl upgrade some time ago

Status changed to 'Confirmed' because the bug affects multiple users.

[Leo Iannacone (l3on)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, I am closing it because the bug has been fixed in the latest development version of Ubuntu - Precise Pangolin. It won't be fixed in previous versions of Ubuntu because the package doesn't fit the requirements for backporting. See https://help.ubuntu.com/community/UbuntuBackports for more information.

https://launchpad.net/ubuntu/+source/mrtg/2.17.3-2ubuntu1

[Leo Iannacone (l3on)]

Ok,

In my last comment I was wrong,

patch seems can be applied to oneiric, natty, maverick.

[Mahyuddin Susanto (udienz)]

Uploaded in maverick, natty, and oneiric. Waiting approval from Ubuntu-SRU

[Clint Byrum (clint-fewbar)]

Hello schoutetens, or anyone else affected,

Accepted mrtg into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Installed the mrtg proposed package. Still getting the same errors.

[schoutetens (stijn-a)]

indeed. the version of mrtg on my system after installing seems to be 2.16.3, the same as the version included in the regular packages. or did I missed something on the procedure for installing proposed packages?

Hi Clint,

It's on a machine that does not have internet access, so I'll have to type it from across the gap... ;)

Yes, that is the updated package. Sounds like the fix did not work....

@schoutetens, did the test also fail for you?

[schoutetens (stijn-a)]

Hi
yes, exact the same results. To me it looks like the packaged version in 'oneiric-proposed' is the same as the packaged version in 'oneiric': v2.16.3 (2010-01-20).
the bug in mrtg is fixed in v2.17.1 (2011-02-18) and later

[Leo Iannacone (l3on)]

Can you please check if this package solves the problem?

I added unpack_sockaddr_in6 as option importing Socket6.

https://launchpad.net/~l3on/+archive/ppa/+build/3131367/+files/mrtg_2.16.3-1ubuntu1.2_amd64.deb

[Leo Iannacone (l3on)]

Anyway... we know that the base version of mrtg has not changed, we are trying to fix bug importing patch from upstream.

And upgrade to 1.7 is not possible in oneiric, unless it got a backport.

[schoutetens (stijn-a)]

Hi

thanks for the effort. I tried installing but i did not succeed. as far as i understand, the perl version currently installed (and needed for apache2) is not compatible with this version. Or probably I did this completely wrong, i'm not that experienced with Linux.
anyway, i had to remove and install mrtg again to get it running again, because the installed version refused to run correctly

a friend pointed me towards the --force-all option of dpkg, so i gave it a 2nd try. dpkg finishes the installation, but the result for mrtg is the same (the same error in the root mailbox as above)

looks to be solved now that I upgraded Ubuntu from 11.10 to 12.04

[Clint Byrum (clint-fewbar)]

Could somebody write a clear test case for this bug so that it can be verified?
